Hace 1 día · Coherence-mixedness trade-offs. Qing-Hua Zhang, Shao-Ming Fei. Quantum coherence constitutes a foundational characteristic of quantum mechanics and is integral to emerging quantum resource theories. However, quantum coherence is severely restricted by environmental noise in general quantum processing, indicated by the loss of information of a ...
Hace 2 días · While strategies to enhance the quantum coherence of plasmonic resonances have attracted a lot of attention in the past, the advent of non-Hermitian optics carries promising possibilities in this ...
Hace 4 días · Beginning out of attempts to extend the understanding of quantum mechanics, the theory has developed in several directions and experimental studies have confirmed some of the key issues. Quantum computing relies on quantum coherence and is the primary practical applications of the concept.
Hace 17 horas · Emitter dephasing significantly affects the performance of solid-state single-photon sources, with acoustic phonons being an important cause of decoherence. Researchers have demonstrated a method to tune and enhance the coherence of photons emitted from a single WSe2 monolayer quantum dot by selectively coupling it to a spectral cavity resonance. Using an open cavity, they achieved…
Hace 4 días · Background Optical coherence tomography (OCT) guidance in percutaneous coronary intervention (PCI) has been shown to improve procedural outcomes. However, evidence supporting its superiority over angiography-guided PCI in terms of clinical outcomes is still emerging and limited. This study aimed to compare the efficacy and safety of OCT-guided PCI versus angiography‐guided PCI in patients ...
Hace 5 días · What is Coherence Therapy? Coherence Therapy, originally called Depth-Oriented Brief Therapy (DOBT), is a constructivist psychotherapy that focuses on resolving the emotional roots of psychological symptoms. Psychotherapists Bruce Ecker and Laurel Hulley developed this approach to therapy.
Hace 5 días · It has been an open question whether quantum coherence can persist through a chemical reaction where bonds dynamically break and form. Now, for the first time, a team of Harvard scientists has demonstrated the survival of quantum coherence in a chemical reaction involving ultracold molecules.
